you tell the sim that the former RCache file is now the Manuall.Cache file ? I assume that Manual…ccc will be ignored, at least we not know whether both have same file-format.
In each case, dont set the size of RC to a useless high value. If you assume issues, disable RCache or set a low size, e.g. 2gig. There are topics about problems in special where users set the RCache file size to extrem values, which nobody need.
